Appendicitis (cont.)

Appendicitis Prognosis

  • With uncomplicated appendicitis, most people recover with no long-term complications.
  • If the appendix ruptures, there is a greater risk of complications, including death. This increase in risk generally is found in the very young, elderly, and those with weakened immune systems, including people with diabetes.
  • Whether a perforated appendix is a significant risk for infertility has not been well established. Some experts recommend that this be considered in young women who might be at risk.

Stump appendicitis is a rare condition where a small amount of remaining appendix tissue from a previous appendectomy becomes inflamed. About 1/10 of 1% of patients who had appendectomy developed stump appendicitis, in one retrospective study. Symptoms are similar to the original appendicitis, with right lower quadrant pain being the most common symptom.
